Wittelsbach Coat of Arms: With the Palatinate the Wittelsbach acquired the lion as an heraldic symbol; the white-and-blue lozenges came to the family when Otto II Wittelsbach, Duke of Bavaria acquired the county of Bogen in 1240

The Wittelsbach dominions within the Holy Roman Empire (Bavaria, The Netherlands and Palatinate) AD 1373 are shown as Wittelsbach, among the houses of Luxembourg which acquired Brandenburg that year and Habsburg which had acquired Tyrol in 1369

On Duke Otto II's death in 1253, his sons divided the Wittelsbach possessions between them: Henry became Duke of Lower Bavaria, and Louis II Duke of Upper Bavaria and Count Palatine of the Rhine. When Henry's branch died out in 1340 the Emperor Louis IV, a son of Duke Louis II, reunited the duchy.

The House of Wittelsbach split into these two branches in 1329: Under the Treaty of Pavia, Emperor Louis IV granted the Palatinate including the Bavarian Upper Palatinate to his brother Duke Rudolf's descendants, Rudolf II, Rupert I and Rupert II. Rudolf I in this way became the ancestor of the older (Palatinate) line of the Wittelsbach dynasty, which returned to power also in Bavaria in 1777 after the extinction of the younger (Bavarian) line, the descendants of Louis IV.

In 1685, the Simmern line died out, and the Catholic Philip William, Count Palatine of Neuburg inherited the Palatinate (and also Duke of Jülich and Berg). During the reign of Johann Wilhelm (1690–1716) the Electoral residence moved to Düsseldorf in Berg. His brother and successor Charles III Philip, Elector Palatine moved the Palatinate's capital back to Heidelberg in 1718 and then to Mannheim in 1720. To strengthen the union of all lines of the Wittelsbach dynasty Charles Philip organized a wedding on 17 January 1742 when his granddaughters were married to Charles Theodore of Palatinate-Sulzbach and to the Bavarian prince Clement. In the imperial election a few days later Charles III Philip voted for his Bavarian cousin Prince-Elector Charles Albert. After extinction of the Neuburg branch in 1742, the Palatinate was inherited by Duke Charles Theodore of the branch Palatinate-Sulzbach.

After the extinction of the Bavarian branch in 1777, a succession dispute and the brief War of the Bavarian Succession, the Palatinate-Sulzbach branch under Elector Charles Theodore succeeded also in Bavaria.

With the death of Charles Theodore in 1799 all Wittelsbach land in Bavaria and the Palatinate was reunited under Maximilian IV Joseph, a member of the branch Palatinate-Zweibrücken-Birkenfeld. At the time there were two surviving branches of the Wittelsbach family: Palatinate-Zweibrücken (headed by Maximilian Joseph) and Palatinate-Birkenfeld (headed by Count Palatine William). Maximilian Joseph inherited Charles Thedore's title of Elector of Bavaria, while William was compensated with the title of Duke in Bavaria. The form Duke in Bavaria was selected because in 1506 primogeniture had been established in the House of Wittelsbach resulting in there being only one Reigning Duke of Bavaria at any given time. Maximillian Joseph assumed the title of king as Maximilian I Joseph on January 1, 1806. The new king still served as an Prince-elector until the Kingdom of Bavaria left the Holy Roman Empire (1 August 1806).

Under Maximilian's descendants, Bavaria became the third most powerful German state, behind only Prussia and Austria. It was also far-and-away the most powerful secondary state. When the German Empire was formed in 1871, Bavaria became the new empire's second most powerful state after Prussia. The Wittlesbachs reigned as kings of Bavaria until 1918. On 12 November 1918 Ludwig III issued the Anif declaration (German: Anifer Erklärung) at Anif Palace, Austria,[1] in which he released his soldiers and officials from their oath of loyalty to him and ended the 738-year rule of the House of Wittelsbach in Bavaria.[2] The republican movement thereupon declared a republic.

Sweden reached its largest territorial extent under the rule of Charles X after the treaty of Roskilde in 1658. Charles' son, Charles XI, rebuilt the economy and refitted the army. His legacy to his son, Charles XII, was one of the finest arsenals in the world, a large standing army and a great fleet. Charles XII was a skilled military leader and tactician. However, although he was also skilled as a politician, he was reluctant in making peace. Although Sweden achieved several large scale military successes early on, and won the most battles, the Great Northern War eventually ended in Sweden's defeat and the end of the Swedish Empire. Charles was succeeded to the Swedish throne by his sister, Ulrika Eleonora. Her abdication in 1720 marked the end of the Wittelsbach rule in Sweden.

King Otto I of the House of Wittelsbach was made the first modern King of Greece in 1832 under the Convention of London, whereby Greece became a new independent kingdom under the protection of the Great Powers (the United Kingdom, France and the Russian Empire). Throughout his reign, Otto faced political challenges concerning Greece's financial weakness and the role of the government in the affairs of the Church. The politics of Greece of this era was based on affiliations with the three Great Powers, and Otto’s ability to maintain the support of the powers was key to his remaining in power. To remain strong, Otto had to play the interests of each of the Great Powers’ Greek adherents against the others, while not aggravating the Great Powers. When Greece was blockaded by the (British) Royal Navy in 1850 and again in 1853, to stop Greece from attacking the Ottoman Empire during the Crimean War, Otto’s standing amongst Greeks suffered. As a result, there was an assassination attempt on the Queen and finally, in 1862, Otto was deposed while in the countryside.

The law of succession to the throne of Greece was defined by a supplementary article to the convention of 7 May 1832 awarding the Greek Throne to Otto I. It instituted a semi-salic order with an important rule preventing the union of the crown on the same head with any other crown, especially that of Bavaria. Under the terms of the succession law, a Wittelsbach claim to the throne would have passed on Otto's death in 1867 to his younger brother Luitpold, who was regent of Bavaria from 1886 to 1912; and after him to Ludwig who became king Ludwig III of Bavaria in 1913. At this point, tracing the claim becomes impossible as the same branch of the Wittelsbach became heir to both thrones, and a subsequent monarch or pretender should have issued a renunciation to one of the two thrones, which none did. In the end, neither Luitpold nor his son Ludwig actively pursued a claim to the Greek throne inherited from Otto I, and the throne of Bavaria itself disappeared in 1918, leaving the future of the claim to be decided by a further arrangement that never occurred.[3]

Joseph Ferdinand of Bavaria, Prince of Asturias, a son of Maximilian II Emanuel, was the favored choice of England and the Netherlands to succeed as the ruler of Spain, and young Charles II of Spain chose him as his heir. Due to the unexpected death of Joseph Ferdinand in 1699 the Wittelsbach did not come to power in Spain, leaving the Spanish Succession uncertain again.

From 1597 to 1794, Bonn was the capital of the Electorate of Cologne and residence of the Archbishops and Prince-electors of Cologne, most of them belonging to the Bavarian branch of the House of Wittelsbach (from 1583 to 1761).
